    Tiller size vs tractor hp

    How much HP is required to run a 6' tiller? I have a 26 HP 4200 - that seems small for a 6' doesn't it? There's a used one for sale near me.

    I did some checking online - King Kutter recommends a minimum of 35HP for a 6' model.

    Does the # of tines effect the HP requirements? The KK 6' has 54 tines, the one I'm looking at has 44 tines.

    If you're interested in more details, read on.

    There's a Deere model 40, 6' tiller for sale near me for $950. The SN indicates 1979. It appears to be in good condition, but it appears to have been painted at some point. The chain cover has been removed at least once - it has new silicon sealant squeezed out. The tines are well worn but would last for a while. The gearbox seems tight. I can't check the bearings as its sitting on the ground but overall, it appears well taken care of.

    The $950 catches my eye. Based on $15 per tine, it would cost $660 to replace them. There might be other items to be replaced but I can't tell. So, it could end up being an expensive tiller at some point.

    I hate to pass on a good deal but I'm pretty sure I can get a new KK 5' model for about $1700. That would be about the largest my tractor could handle.

    Thoughts?

    Oh, and if anybody wants more details on where to get it, PM me.

    Thanks.

    Is that PTO HP, or gross engine HP? Is your trans Hydro or Gear?

    If that's PTO HP, I'd say you could get away with a 6' tiller. If it's engine HP, a 5' tiller would be more ideal. I run a 5ft King Kutter2, on 25 PTO HP, and it doesn't even know it's back there, and I can sink it pretty good. I've ran the same tiller on 16 PTO HP (19 engine HP), of my old Kubota B8200D (gear shift), and it could handle it. However, it was smaller bites, shallower depth, and more passes to get the same results.

    So you're 19-20 PTO HP then?
    A 5ft tiller would be more ideal, then a 6. But, sometimes deals are hard to pass up, I get it. Most people say 5 HP per ft of implement, but I think 4 is just as doable, so long as the implement isn't to big in physical dimensions.

    Lots of variables. Ground speed, tire type, depth, soil conditions, unbroken ground or previously engaged, horsepower, tine count, width, etc. etc.

    Agree with this. Also depends on your intended use. If you are just tilling an established garden area every year, you can run a larger tiller. If you are going to be breaking new or hard packed ground, you probably want a smaller tiller...or you will be making many shallower passes to work your way as deep as you want.

    If the tiller is cheap enough,, buy it,,
    if you run out of power,, take off a few outside tines,, in effect, the tiller will be five foot,,,

    If it were me and seller has a tractor to mount it to, I'd want to see it run, then judge it. Take $750 in big bills with you and show it to the guy if you like the tiller. See what happens.

    Thank you

    Thanks to all for the excellent advice. After discussing with the finance committee, I've decided to pass on this one. Here's the reasons:
    Yes, I could buy it and I think I could probably get it at a reasonable price for the unit. And, on the down side:

    • It is way too big for my tractor size. A 5' model is probably as big as I can go. Yes, I could buy a bigger tractor.
    • I don't need it right now. We don't garden. We want to garden when we retire, but we current live on a wooded lot and gardening isn't an option. We're going to move in a few years but I'm sure I can find one between then and now.
    • I don't need another project. This implement is 40 years old and will likely need some work. For now, it would just sit, which doesn't seem like a good idea.
    • It will cost $660 to replace the tines. The tines are at least 50% worn. I could get many years out of them but not many years of a lot of tiling.
    • While the price is low, and I think I can get a 5' model cheaper in the long run. I can buy a new (or newer used) KK. Yes, this one is stll cheaper up front, If I replace the tines and some bearings, possibly gears and a new chain, It will be close. And my time is worth some small amount of money. So, I'm not convinced its a bargain, even at $750.
    • For as often as I would need one, even if we were gardening, I can rent one. My local rental place has them for $100 per day. I can do a lot of tilling in a day for $100 and they will do all the maintenance.
    • I have an older troy bilt horse that runs well. It will make a better option when we start gardening. We may try gardening and find we really don't like it as much as we thought we would.


    Thanks again.

    Just as FYI...
    I had a 2025R Gen 1 (25HP but 21 at pto I think)

    I rented a tiller. When I went to pick it up the only think they had was a brand new JD 72" tiller.
    I knew it was too big for my tractor, but I couldn't resist the chance to take home the shiney new tiller and get it dirty. I figured I could borrow a larger tractor if needed.
    So...With a little adjustment I was able to hook up the tiller. I was tilling fresh sod, so I knew I had to go easy and take just a few inches of dept at each pass.
    The tractor and tiller worked great. I was impressed.
    However, one thing is for sure. That tiller is TOO BIG for anything but occasional use.

    A 60" would be ideal for all around use. Maybe even 48" max in tough soils.

    Just my real world observation.
